dp1 = fraction(dp1)

DESCRIPTION

fraction returns the fractional value of its real or double precision argument as a normalized fraction in the interval [½, 1). 

If the value of the argument is 0.0 then fraction returns 0.0. 

For any argument x the following is true: x = fraction(x) ∗ 2 ∗∗ exponent(x)
